JoAnn's sells most of the different brands. I have tried almost all of them and much prefer Wonder Under (also known as Pellon 805) because it is the easiest to machine or hand stitch through and does not gum up needles at all. It also bonds tightly and tends to result in fewer frayed edges. I use it a lot with art quilts and do not always stitch the edges since the pieces will not be washed.
